DETAILED DESCRIPTION

Embodiments in this disclosure generally relate to decontamination(e.g., cleaning) and/or sanitization.

Anolyte and catholyte can be used in place of these toxic chemicalspreviously discussed. Anolyte and catholyte are not only non-toxic andconsumable, but can also be easily produced on-site at a facility thatuses anolyte and catholyte. This makes anolyte and catholyte productionand use a cost-effective solution for the sanitization and cleaningneeds of a facility.

FIG. 1 illustrates, by way of example, a diagram of an embodiment of asystem 100 for decontamination and/or sanitization. The system 100 asillustrated includes a conduit 101, a water inlet 102, a fluid outlet104, a catholyte tank 142, and an anolyte tank 144. The water inlet 102is optional. The system 100 as illustrated further includes a sensor108A and 108B, a pump 112A, 112B, and 112C, a first valve 126A and 126B,and a second valve 116A and 116B. The sensor 108A and 108B, a pump 112A,112B, and 112C, the valve 126A and 126B, and the check valve 116A and116B are optional.

The conduit 101 may be a hollow, usually annular, length of materialthrough which fluids may flow without leaking out of sidewalls of theconduit 101. The material of the conduit 101 may include a polymer,ceramic, metal, a combination thereof or other material. An innerdiameter of the conduit 101 and a flow rate of the fluid in the conduit101 may determine a volume of fluid that may be provided to the outlet104.

The water inlet 102 provides potable water to the conduit 101. Potablewater complies with 40 C.F.R. 121, the Safe Drinking Water Act andNational Primary Drinking Water regulations. Treated water may be waterwith ≤1 grain of hardness (<17.1 parts per million (PPM) total dissolvedsolids (TDS)).

The water from the water inlet 102, in one or more embodiments may bereverse osmosis water. In one or more embodiments, the water from thewater inlet 102 includes less than one part per million (ppm) of each ofhardness, fluoride, iron, magnesium, and borax and borate. In one ormore embodiments, a flow rate of the water from the water inlet 102 maybe between about 22-30 gallons per hour. In one or more embodiments, thewater from the water inlet may be at a pressure of about forty-five tofifty pounds per square inch (psi).

The pump 112C may be a variable displacement pump, dosing pump, or thelike. A pump may be generally an electro-mechanical device using suctionor pressure to move fluid(s). A dosing pump may be a displacement pumpthat provides a set flow rate of a fluid. The flow rate on a dosing pumpmay be fixed or variable. A variable displacement pump convertsmechanical energy to fluid energy. The displacement, or amount of fluidprovided by the variable displacement pump or dosing pump may be variedwhile the pump is running.

The valve 116C may be a one-way valve. A one-way valve allows fluid toflow from the inlet 102 and/or pump 112C to the adapter 120 and/oroutlet 104. A one-way valve prevents fluid from flowing from the adapterand/or outlet 104 to the pump 112C and/or inlet 102. Other types ofvalves may be used in other embodiments.

The catholyte tank 142 holds a decontamination fluid, such as catholyte.Catholyte may be an electrolytically generated (activated) amphotericsurfactant(s). A precursor to catholyte can include salt dissolved inwater. An oxidation reduction potential (ORP) of catholyte may betypically in a range of about negative two hundred millivolts to aboutnegative one thousand one hundred millivolts. The salt(s) in the watermay include sodium chloride (NaCl) to any other mineral salts in eithera specific (e.g., 99.9% NaCl) or other proportion, as in ordinarydrinking water.

The catholyte tank 142 as illustrated includes the sensor 108A. Thesensor 122, in one or more embodiments may be a level sensor. A levelsensor provides data indicative of a level of catholyte in the catholytetank 142. The sensor 108A may include an ultrasonic sensor, capacitancesensor, hydrostatic pressure, or other level sensor. The sensor 108A maybe submersible or dry.

The pump 112A may be similar to the pump 112C. The pump 112A may movecatholyte from the catholyte tank 142 in the conduit 101. The pump 112Amay provide the catholyte to the valve 126A. The valve 126A may be influid communication with fluid from the pump 112A and/or the catholytetank 142. The valve 126A, when open, provides a path for catholyte toflow to the outlet 104. When closed, the valve 126A prevents catholytefrom flowing to the outlet 104. The valve 126A may be opened or closedautomatically, such as by an actuator, or manually. The valve 116A, inone or more embodiments, may be a two-way valve (2WV) or other type ofvalve.

The valve 116A may be a one-way valve that allows fluid flow in only onedirection. The valve 116A may allow the catholyte from the catholytetank 142 to flow therethrough to the outlet 104 and prevents fluid fromflowing from the outlet 104 or adapter to the 2WV 126A, pump 112A,and/or catholyte tank 142.

The anolyte tank 144 holds a sanitization fluid, such as anolyte.Anolyte may be an electrolytically generated (activated) amphotericsurfactant(s). A precursor to catholyte can include salt dissolved inwater. An oxidation reduction potential (ORP) of catholyte may betypically in a range of about negative two hundred millivolts to aboutnegative one thousand one hundred millivolts. The salt(s) in the watermay include sodium chloride (NaCl) to any other mineral salts in eithera specific (e.g., 99.9% NaCl) or other proportion, as in ordinarydrinking water. Anolyte may be an electrolytically generated (activated)amphoteric surfactant. Similar to catholyte, a precursor to anolyteincludes brine (salt dissolved in water. The salt used may includesodium chloride (NaCl) or other mineral salt in generally anyproportion. The ORP of anolyte may be typically in a range of aboutpositive five hundred millivolts to about positive one thousand twohundred millivolts.

The anolyte tank 144 as illustrated includes a sensor 108B. The sensor108B may be a level sensor. A level sensor provides data indicative of alevel of anolyte in the anolyte tank 144. The sensor 108B may include anultrasonic sensor, capacitance sensor, hydrostatic pressure, or otherlevel sensor. The sensor 108B may be submersible or dry. The sensor 108Bmay be similar to the sensor 108A.

The pump 112B may be similar to the pump 112C. The pump 112B may moveanolyte from the anolyte tank 144 in the conduit 101. The pump 112B mayprovide the anolyte to a valve 126B. The valve 126B may be in fluidcommunication with fluid from the pump 112B and/or the anolyte tank 144.The valve 126B, when open, provides a path for anolyte to flow to theoutlet 104. When closed, the valve 126B prevents anolyte from flowing tothe outlet 104. The valve 126B may be opened or closed automatically,such as by an actuator, or manually. The valve 126B, in one or moreembodiments, may be a 2WV or other type of valve.

The valve 116B may be a one-way valve that allows fluid flow in only onedirection. The valve 116B allows the anolyte from the anolyte tank 144to flow therethrough to the outlet 104 and prevents fluid from flowingfrom the outlet 104 or adapter 120 to the valve 126B, pump 112B, and/oranolyte tank 144.

The catholyte and/or the anolyte may be provided through an electrolysisdevice. An electrolysis device takes dilute brine (saltwater) as input,applies an electrical current to the received brine, and producesconcentrated anolyte and catholyte. Saltwater, anolyte, and catholyteare examples of electrolytes.

The adapter 120 may be a multiple input component with one or moreoutputs. The adapter 120 may provide a path through which catholyte fromthe catholyte tank 142 may be mixed with water from the water inlet 102and/or anolyte from the anolyte tank 144. In one or more embodiments, apath of the adapter 120 through which the catholyte and water are mixedand a path of the adapter 120 through which the anolyte and water aremixed may be separate, such that catholyte and anolyte are not mixed inthe adapter 120. In such embodiments, the adapter 120 includes fourinputs (one for catholyte, one for anolyte, and two for water) and oneor more outputs (one for catholyte and water mixture and one for anolyteand water mixture, or one for both the catholyte and water mixture andanolyte and water mixture). In one or more embodiments, the adapter 120includes three input paths that combine and are provided in a singleoutput.

The outlet 104 receives the catholyte, anolyte, and/or water, such asmixed. The outlet 104 may include a valve, such as may be automaticallyor manually controlled. The outlet 104 may include a structure similarto a faucet, for example. The outlet 104 may include one or more valvesto control a heat of a fluid provided to the outlet 104. The outlet 104may include one or more valves to control a volume of a fluid providedto the outlet 104. The outlet 104, in one or more embodiments, may be ahand hygiene sink, appliance, and/or appurtenance (HHSA). The outlet 104may include an enclosed atmospherically controlled chamber thatcaptures, contains, condenses, drains, and/or dries one or moreaerosol(s) generated in a decontamination and/or sanitization process.Such an enclosure may help reduce risk(s) of contamination of a user,their attire, other surfaces, and/or other object or environment aroundthe outlet 104. The outlet 104, in one or more embodiments, may betransparent. In one or more embodiments, the outlet 104 may include anultrasonic nozzle, such as to help activate the catholyte and/oranolyte. The nozzle may provide bubbles, such as may provide kineticenergy that enhances the decontamination and/or sanitization.

In one or more embodiments, the outlet 104 may include one or moreimmersion baths (e.g., a catholyte immersion bath and/or an anolyteimmersion bath) in which a user may submerge their hands or other partto be decontaminated and/or sanitized. The immersion bath(s) may includeone or more ultrasonic transducers to produce sound that may be incidentthereon. The ultrasonic transducers may enhance a decontamination and/orsanitization by the catholyte and/or anolyte immersion bath,respectively, such as by helping activate the catholyte and/or anolyte.

In embodiments that do not include one or more of the pumps 112A-C, thefluid mobilized by the respective pump 112A-C may be mobilized by agravitational force or Venturi. In embodiments that use gravitationalforce, the catholyte tank 142, anolyte tank 144, and/or water inlet 102may reside at an elevation that may be higher than the elevation of theoutlet 104. The anolyte, catholyte, and/or water may be provided to theoutlet 104, such as by opening a valve of the valve 126A-B and/or theoutlet 104. In embodiments that use Venturi, the conduit 101 may includea venture tube. A Venturi tube includes one or more constrictions. Aflow rate of a fluid in the region of the constriction increasesrelative to non-constricted regions, thus moving the fluid through thetube.

While the water inlet 102 is illustrated as including a single conduitconnected thereto. The water inlet 102 may include a hot water conduitand a cold water conduit connected thereto. In such embodiments, theadapter 120 may include four inputs and a one or more outputs. One inletfor catholyte, one inlet for anolyte, one inlet for cold water, and oneinlet for hot water. The outlet(s) of the adapter 120 may include asingle outlet for combinations of hot water, cold water, catholyteand/or anolyte, or two outlets, one for combinations of hot water,anolyte, and/or catholyte, and a second outlet for combinations of coldwater, anolyte, and/or catholyte.

The system 100 as illustrated includes optional sensor(s) 122A, 122B,122C, 122D, 122E, and/or 122F, an optional dryer 124, and an optionalcamera 128. The sensor(s) 122 may include one or more of a flow sensor,free available chlorine sensor, pH sensor, conductivity sensor, or thelike.

A flow sensor determines a volume of liquid displaced per unit time.Flow can be measured by determining a velocity of liquid over a knownarea or through a known volume. Alternatively, flow can be measured bydetermining forces produced by a flowing fluid as it overcomes a knownconstriction and inferring the flow rate based on the forces produced.

Free available chlorine may be generally expressed in PPM. Freeavailable chlorine sensors may be placed in a flow stream orsubmersible. A free available chlorine sensor provides an indication ofan amount of unbound chlorine in a fluid.

A pH sensor measures a concentration or activity level of hydrogen ionsin an aqueous solution. The data from a pH sensor indicates how acidicor basic a solution is. pH means potential hydrogen and a measure of pHranges from acid (a minimum pH of zero) to an alkaline base (a maximumpH of fourteen).

A conductivity sensor determines conductivity of an aqueous solution.The conductivity can be useful for determining a concentration ofdissolved chemicals, such as the concentration of salt in a fluid.Conductivity is a measure of a solution's ability to carry an electriccurrent. Conductivity is the reciprocal of the resistance of a solution.

The camera 128 may capture images, audio, and/or video of an area thatincludes the outlet 104 and a user of the outlet 104. The field of viewof the camera 128 may include one or more hands, arms, face, or otherbody part of the user.

The dryer 124 provides a user an ability to dry a portion of their body.For example, the user may decontaminate their hand, arm, or other bodypart by placing it in a stream of fluid from the outlet 104, dry theirbody part using the dryer 124, sanitize their body part by placing it inanother stream of fluid from the outlet 104, and dry their body partagain using the dryer 124. The dryer 124 may include a towel, a napkin,an air blowing device, or the like.
